Abandoned South Island tunnel

After hearing a rumor about a mysterious train tunnel in the South Island of New Zealand myself and DerelictNZ went out to investigate.
Sadly our first attempt was a bit of a fail after spending a whole afternoon trying to find it but after some more research urbexcentral returned and this time success!

The tunnel was fully bored and constructed in the early 1940’s however it was given up on after some of the walls started breaching. The damage inside the tunnel is pretty substantial and it felt pretty unsafe to lurk through, from the crazy angles and curvature in the tunnel I suspect the kaikoura earthquake in 2016 played a part in the damage.
